Should I move from 1.11 to 2 before deploying on a server ?

I have almost finished a Django project I have been developing. I have started on 1.11 but now I see that there is Django 2.

I am wondering if I should move to Django 2 before putting my project on a server.

Making a currency/point system for a site?

Hey my friends and I are often betting on stuff (like who will win a football game or who will get drunk first) so I thought I would make something like a 'betting' app for us to bet like 2 points/coin on something. Does anyone know how to make currency or point systems and or a betting system?

Seeking advice on putting together the model structure for a 1-to-1 chat using Channels.

I'm struggling with implementing the data structure for a chat system. I've looked through most of the popular tutorials but I'm still having trouble applying it to my own use-case.

I am looking to allow a chat system similar in structure(not UI) to facebook or AIM from back in the day--one on one messaging, with message persistence, and a user able to have many chats.

The tutorials I've looked through have conflicting suggestions.
Given that I already have a model called `Pair` which has two `ForeignKeys`, named `requester` and `accepter`, each pointing to a `User`, how might I structure the messages or rooms around this `Pair`? (structuring around `Pair` isn't mandatory, I just thought it may be convenient)

What I've brainstormed:
1) Have a single `Room` model with a FK to the `Pair` model, and two TextFields for the messages: `to_accepter` & `from_accepter` to denote the messages belonging to the appropriate user.

2) Have a `Room` model and a separate `Message` model. The message will have an FK to the room, and have fields: `sent_from`(message sender), a timestamp(to eventually organize the list of displayed messages, and the TextField.

Is there an ideal way to go about this? I'm open to any suggestion.
Thanks in advance.

Redefining or updating a migrated model

I find myself modifying and changing features on some of my models often and sometimes get this message because I changed a foreign key:

You are trying to add a non-nullable field 'client' to env_contact without a default;
we can't do that (the database needs something to populate existing rows).

Please select a fix:

1) Provide a one-off default now (will be set on all existing rows with a null value for this column)

2) Quit, and let me add a default in models.py

Usually I have mock data or no data in these tables. Is there a way to delete the tables and migrations and redefine the model from scratch without doing a data dump, nuking the db and then resetting the models?

Having trouble with static files in a docker-django build on the Docker Toolkit

Posting this in both Django and Docker subs. I have tried a lot of combinations of setting static_url/dirs/and roots but so far no luck. File structure is wonky but I think it's right:

-US
--Static
---USApp
----/style.css
--USPro
---settings.py

end of my settings file currently looks like this:
STATIC_URL = '/Static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR, "Static/USApp"),
]
STATIC_ROOT = "/US/Static/USApp/"

any help would be greatly appreciated!

Index page contains data only on first visit; refresh and subsequent visits are empty

Hello all and thanks for taking time to read into this issue I'm having.

I have a small web app that is passing an object to my index page, the index page loops and renders the object into a nice pretty table.

Here is my route:

@app.route('/', methods=['GET'])
def index():
return render_template('index.html', cursor=cursor, current_time=datetime.utcnow())

the "cursor" object is really a mongodb query that was created just above the route descriptor:

cursor = db.ipv4.find().sort([("prefix", 1), ("prefixLen", -1)])

This is ran through the index.html page's template, which looks like this:

{% for route in cursor %}
<tr>
<td>{{ route.prefix }}</td>
<td>{{ route.prefixLen }}</td>
<td>{{ route.aspath }}</td>
</tr>
{% endfor %}

The result is a beautiful table of my previous IPv4 unicast table, and it renders great, but only once! Any second visitor or a refresh to the page shows that there are no rows rendered for my table (looking at the page's source).

My theory is that there is something that I'm missing when passing the cursor variable into the view function, something that currently limits it to run just once. I am new to Flask so it is likely that I am mistaken and would greatly appreciate any pointers.
